Familiarfexamples in theprior art have comprised hemispherical or other thick' but'- tonsmade of fibre, pearl, vitreous and other `compositions and having wire shanks embeddedin the -body ofthe button, which are unsatisfactory in appearance; and have .i also comprised buttons `of hard material,

v"such as vegetableivory,` having a headed wire shank inserted through a hole inthe f centre ofthe button. These latter are satcentral drill hole. v

bleior fusible adhesive 9 and applying there-.

:5 v p a vrable metallic lustre paint will serve, whether the fluid binder is a soluble ora fusible adhesive. In some eases, prefer the metallic body to be .of silver or aluminium powder or flakes, and I `intend to referto any of these metallic paintsy or` enamels by *they termlustre enamel.

l. A button of the same form as that illustrated vin Fig. 1 maybe Constructed with many of the same advantages, as V*shown in Fig. 2, by coating the mound 6 with a soluto a round spot of foil 10 of azsuitablenonoxidizing' metal.

As shown in l' for the vsame purposes by providing a mound 12 in a central' position having undercut edges ,13 over which a thin metal cap 14 of' suitable dimensions is sprung.

i central spot, may be lacquered or varnished after application of the lus-trous vspot.

In each of the above cases, the button is provided with the usual loopshank consisting of a piece of Wire 15. which may be bent "in the form shown, and having its divergent ends 16 embedded in the substancel of the button.

y ivill rbe observedthatthe appearance Fig.- 3, Ilmay form a buttony The 'Whole' button, in each. oit .these instances, or the of the old-artbutton of 5 isclosely imif tated by the new device, without weakening its structure; as is the case'when the shortshank pin 17 of Fig. 6 is employed, as here tofore, to imitate the appearance ed shank. y,

The central spot in the button is protected ofthe headfrom Wear by the ridge 4, its lustre being ,n

as durable as thatof the head of a metallica` shank.

What I claim is: f y y, 1. A. button comprising a body having an integral contour presenting'an annular. ridge and a central mound Wholly Within and beneath the plane defined by the said .annular ridge having thereon a lustrous metallic` coating, the button being 'provided With a loop shank having its ends embedded in the substance thereof. i n

2. A button having a molded composition body with an annular face ridge and central mound, the mound having thereon acoating of lustre enamel, and the body having ein bedded therein the ends of a Wire loop shank,"
